Convergence (2011) for Alto Saxophone and Electronics


Convergence was written for saxophonist Heidi Radtke.  I was interested in the interaction between the intrinsic qualities of electronic and acoustic mediums.  In this piece, I used the electronics and saxophone as equal partners to take turns in background and foreground roles and to create timbral illusions. I also explored the altissimo range (very high notes) on the saxophone, which can provide unique timbral effects and is technically challenging.


There are two main ideas: trills or noodling figurations, and sustained notes.  These are mutated into each other throughout the piece.  The overflowing of recorded saxophone sounds at the climax is morphed into the live saxophone at the end.  Most of electronic sound materials used in the piece are a manipulation of saxophone sounds pre-recorded by Heidi.  The piece is dedicated to Heidi, whose passion for new music inspires me.

Convergence (2019) for Bb Clarinet and Electronics


Convergence for Clarinet and Electronics는 라이브로 연주되는 클라리넷과 미리 만들어진 전자음향의 다양한 얽힘으로 빚어지는 여러 색채적 환영 (timbral illusions)이 결국, 이 곡의 처음이자 마지막인 클라리넷으로 다시 수렴되는 과정을 탐구한 작품이다.


곡 전반에 걸쳐 클라리넷과 전자음향은 전경과 배경을 넘나들며 각자 여러 다른 역할을 수행하고, 때로는 누가 누구인지 모를 모호한 청각적 착각을 불러일으킨다. 이러한 두 매체의 다양한 방식으로의 교류함은 이 곡의 첫 부분에 제시된 음악적 아이디어 (구불구불한 선과 지속음)의 성격을 계속해서 변화시키며 매 순간마다 다른 감정을 불러일으키는 음악적 장치가 된다.
